RPM Spec for Nomad

RPM build for creating Nomad packages for use in the ENA environment.

Building

The RPMs may be built with Docker, Vagrant, or manual.

Whatever way you choose you will need to do a few basic things first.

git clone https://github.com/myENA/nomad-rpm  ## check out this code
cd nomad-rpm                                  ## uhh... you should know
mkdir -p artifacts                            ## prep the artifacts location

With Docker

docker build -t ena/nomad-rpm .                                ## build the image
docker run -v $PWD/artifacts:/tmp/artifacts -it ena/nomad-rpm  ## run the image and build the RPMs

With Vagrant

vagrant up       ## provision and build the RPMs

Manual

cat build.sh     ## read the script

Result

Two RPMs will be copied into the artifacts folder:

1. nomad-<version>-<release>.el7.centos.x86_64.rpm - The binary and systemd service definition (required)
2. nomad-config-<version>-<release>.el7.centos.x86_64.rpm - Example agent configuration (recommended)

Running

1. Install the RPM(s) that you need
2. Review and edit (if needed) /etc/sysconfig/nomad and associated config under /etc/nomad.d/* (config package)
3. Start the service and tail the logs: systemctl start nomad.service and journalctl -f --no-pager -u nomad
4. Optionally start on reboot with: systemctl enable nomad.service

Configuring

Config files are loaded in lexicographical order from the config specified in /etc/sysconfig/nomad (config package). You may modify and/or add to the provided configuration as needed.
